Silicon carbide powder

Abstract

The present invention is a silicon carbide powder with which it is possible to obtain favorable results in terms of the reaction performance of carbon and silicon, the amount of free carbon (FC), and the yield of the silicon carbide powder. In a mixture containing a silicon source, a carbon source, and a catalyst, the silicon source is methyl silicate; and when the mixture is 100 weight %, the weight % of the carbon source is 33 weight % or more and 39 weight % or less, the weight % of silicon source is 55 weight % or more and 62 weight % or less, and the weight % of the catalyst is 3 weight % or more and 10 weight % or less.

1 . A silicon carbide powder wherein
 in a mixture containing a silicon source, a carbon source, and a catalyst, the silicon source is methyl silicate, and   when the mixture is represented by 100 weight %,
 a weight percentage of the carbon source is 33 weight % or more but 39 weight % or less, 
 a weight percentage of the silicon source is 55 weight % or more but 62 weight % or less, and 
 a weight percentage of the catalyst is 3 weight % or more but 10 weight % or less. 
   
     
     
         2 . The silicon carbide powder according to  claim 1 , wherein the weight percentage of the carbon source is 34.5 weight % or more but 38 weight % or less, when the mixture is represented by 100 weight %. 
     
     
         3 . The silicon carbide powder according to  claim 1 , wherein the weight percentage of the silicon source is 57 weight % or more but 61 weight % or less, when the mixture is represented by 100 weight %. 
     
     
         4 . The silicon carbide powder according to  claim 1 , wherein the weight percentage of the catalyst is 3 weight % or more but 8 weight % or less, when the mixture is represented by 100 weight %.
